Continuous release in partially confined atmosphere

Event

Event ID
27
Quality
Description
Damage of shipping containers of a ship, due to the reaction of phosphor pentoxide with wine, which lead to the production of phosphoric acid and hydrogen. The overpressure was successfully eliminated by ventilating the storage space.

Initiating cause
Run-Away Reaction
Root causes
Root CAUSE analysis
The INITIATING CAUSE was a chemical reaction having hydrogen as product, which ignited.
The ROOT CAUSE could be tentatively assigned to an inadequate risk assessment, able to identify this accidental scenario.

Emergency & Consequences

Number of injured persons
0
Number of fatalities
0
Emergency action
Rescue units were on site but they did not make an attempt to extinguish the fire to avoid the formation of a hydrogen cloud. The affected unit was depressurised. After 50 minute the leak was closed and the fire extinguished. Shortly afterward the alarm was terminated.
